Peoria sits on bluffs above the Illinois River, but lower-elevation neighborhoods along the riverfront are repeatedly flooded. The Illinois River has flooded downtown Peoria multiple times in the past decade. Spring flooding from snowmelt and rain is the primary annual flood event — the river can rise 25–30 feet above normal pool. Bluff-top neighborhoods face severe basement infiltration and foundation hydrostatic pressure during prolonged wet periods. Older housing stock (1920s–1960s) throughout the city has cast iron drain lines subject to root intrusion and collapse.
Flood-prone areas: Lower Peoria and riverfront are highest flood risk. Sheridan, Richwoods, and bluff-top neighborhoods have lower river flood risk but face basement infiltration. Peoria Heights and Dunlap are higher-ground suburbs.
